"Pud" (Bobs Watson) and his wheelchair-confined "Gramps",
Julian Northrup (Lionel Barrymore), are inseparable buddies. They pal
around all day long, and joke irreverently, much to the consternation
of the grandmother, Nellie (Beulah Bondi). When Pud's parents are killed
in a car accident, he is left to the care of the elderly couple.

When Pud's conniving aunt Demetria (Eily Malyon) learns that Pud is
the beneficiary of a $55,000 life insurance policy, she schemes to
adopt him and take him away from the grandparents.

In the front yard, Pub climbs
the old apple tree and Gramps jokes that he cannot come down and he
says so. Pud discovers that it is true, he indeed cannot extricate
himself from the tree until Gramps says that he is free.

Grandma Nellie lies, exhausted, in her bed and a dapper "Mr.
Brink" (Cedric Hardwicke) appears in her room. He tells her that it
is time for her to come with him. She seems to understand, takes his
hand, and she dies.

With the grandmother now gone, Demetria is more determined than ever
to remove Pud from the home for her own gain. To show the authorities
a better side, Gramps decides to take Pud to Sunday church services.
But, as he waits for Pud in front of the house, Mr. Brink appears to
take the grandfather as well. Gramps tells Mr. Brink that he will go,
but requests that Mr. Brink get him one of his beloved apples from
the tree. As Brink climbs the old tree, Gramps pronounces that he cannot
descend. Mr. Brinks realizes his predicament, but is philosophical,
even cordial about it.

Demetria brings the grandfather's doctor, Dr. James Evans, (Henry
Travers) and lawyer (Grant Mitchell) to the house to convince them
that the old man is an unfit guardian. They are convinced when they
witness him talking to Mr. Brink in the tree, who they can neither
see nor hear. They return with a burly attendant from an asylum to
remove Gramps by force. He tries, unsuccessfully, to convince them
that Death, in the form of Mr. Brink, is now incapacitated in the tree
and that no one will die as long as he is there. Gramps grabs a handgun
from a drawer and shoots the asylum attendant.

Later, in the hospital, he revives and is perfectly healthy. Dr.
Evans, amazed, does his own experiments with the apple tree and becomes
convinced of the truth. He realizes that Gramps must allow Mr. Brink
to come down or people all over the world will suffer for eternity
without the relief of death. He returns with the sheriff to forcibly
remove Gramps, in the hope that he will relent when faced with losing
Pud.

But the despondent Pud runs off, and the others are unable to locate
him. Pud comes out of hiding near the tree, and Mr. Brink tricks him
into climbing onto the fence surrounding the tree. Pud loses his balance
and falls, severely injuring his spine, with the prognosis of never
walking again.

Gramps, in his wheelchair, takes the injured Pud to the yard and announces to Mr. Brink that he is free to descend from the tree. Mr. Brink puts
his hand on Pud, who stands on his own and is seemingly healed. Then
Mr. Brink takes Gramps' hand, who stands on his own as well. He and
Pud walk off into an idyllic eternity, with the voice of Granny calling
to them as they walk together.
